PIPE CLAMP OR COUPLING CULLAR.

Specification of Letters Patent.

Patented May 18, 1909.

Application filed July 23, 1907. Serial No. 385,127.

To all whom it may concern:

Be it known that I, JOHN T. EVERETT, a citizen of the United States,residing at Basin, in the county of Bighorn and State of Wyoming, haveinvented a new and useful Pine Clamp or Coupling Collar, of which thefollowing is a specification.

This invention relates to pipe couplings and has for its object toprovide a con1para-,

tively simple and thoroughly cfiicient device of this characterespecially designed for uniting sections of pipes employed for conveyingwater in irrigating ditches and the like.

A further object of the invention is to provide a coupling including achannel ring adapted to engage the interior walls of adjacent pipesections at the over-lapped ends thereof and having a clamping member orrod co-acting therewith and engaging the exterior walls of said pipesections so that by adjusting the clamping member the overlapped ends ofthe pipe sections will be forced within the seating groove of thechannel ring and thus form a water tight joint between the several pipesections.

A still further object of the invention is generally to improve thisclass of devices so as to increase their utility, durability andefiiciency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claim.

In the accompanying drawings forming a part of this specification:Figure 1 is a side elevation of a clamp or coupling constructed inaccordance with my invention showing the same in position on a pipe.Fig. 2 is a transverse sectional view taken on the line 22 of Fig. 1.Fig. 3 is a longitudinal sectional view. Fig. 4 is a transversesectional view taken on the line 44 of Fig. 2.

Similar numerals of reference indicate corresponding parts in all of thefigures of the drawings.

The improved coupling forming the subj ect matter of the presentinvention is principally designed for uniting two or more sections ofpipe so as to produce a continuous culvert for conveying water inirrigating ditches and the like, and by way of illustration is shownapplied to mating pipe sections one of which is indicated at 5 and theother at 6.

The pipe sections 5 and 6 are preferably cylindrical in contour andformed of galvanized iron or other suitable material, said sectionshaving their inner ends over-lapped and their adjacent longitudinaledges provided with interengaging hooks constituting a lap joint '7.

Bearing against the interior walls of the pipe sections 5 and 6 anddisposed at the over-lapped ends thereof is a reinforcing member 8preferably in the form of a ring or annulus and having a circumferentialseating groove 9 formed therein defining spaced annular flanges 10adapted to bear against the adjacent walls of the pipe sections, asshown.

Surrounding the exterior walls of the pipe sections at the reinforcingring 8 is a clamping member or rod 11 having its opposite ends threadedat 12 for engagement with suitable clamping nuts 13. The threaded endsof the rods pass between spaced ears or lugs 14 extending laterally froma clip or bracket 15, while the nuts 13 bear against the inner faces ofthe ears 14 so that by adjusting said nuts the rods 11 will force theoverlapped ends of the pipe sections in engagement with the seatinggroove 9 and thus form a water tight joint between the several pipesections.

The clip or bracket 15 is provided with a longitudinally disposed rib 16the lower end of which is curved or rounded and adapted to depress theover-lapped ends of the metal constituting the pipe sections within theseating groove or channel of the reinforcing ring when the nuts 13 areadjusted, as best shown in Fig. 4c of the drawings.

in using the device the pipe sections are arranged in horizontalalinement with the end of one section over-lapping the adjacent end ofthe mating section, after which the reinforcing rings 8 are positionedwithin the pipe sections and disposed at the over-lapped ends thereof.The clamping rod 11 is then positioned on the exterior walls of the pipesection and the nuts 13 adjusted on the threaded ends of the rod thuscontracting said rod and causing the latter to force the over-lappedends of the pipe sections within the seating groove of the reinforcingmember, as best shown in Figs. 2 and 3 of the drawings.

Attention is here called to the fact that the ring 8 serves to reinforceand strengthen the pipe and brace the latter against external pressure.It Will also be observed that the spaced annular flanges 10 of thereinforcing ring bite into the metal on each side of the lap joint 17When the clamping rod 11 is adjusted so as to effectually prevent theescape of water at the juncture of said sections, the reinforcing ringforming in effect a housing for the over-lapped ends of the pipesections.

From the foregoing description it Will be seen that there is provided anextremely simple, inexpensive and efficient device admirably adapted forthe attainment of the ends in view.

Having thus described the invention what is claimed is:

The combination with mating pipe sections having their inner endsover-lapped, of an an nular reinforcing member disposed Within the pipesections at the over-1apped ends thereof and provided With spacedcircumferential flanges of uniform cross sectional diameter and providedwith flat peripheral contact faces, one of Which bears against one ofthe interior walls of one of the pipe sections, the other contact beingarranged to bear against the interior Wall of the other pipe section, a

bracket engaging the exterior Walls of said pipe sections and providedwith a central longitudinally bowed rib extending between the flanges ofthe reinforcing member and having oppositely disposed shoulders adaptedto force the interior Walls of the pipe sections into engagement withthe flat contact faces of the flanges, said bracket being provided Withoppositely disposed lugs having slots formed therein and opening throughthe tops of said lugs, a clamping rod surrounding the exterior walls ofthe pipe sections and provided With threaded terminals passing throughthe slots in the bracket, said clamping rod being disposed in alinementith the longitudinally bowed rib on the bracket and forming acontinuation thereof, and nuts engaging the threaded terminals of therod and bearing against the lugs for forcing the pipe sections getweenthe flanges of the reinforcing mem- In testimony that I claim theforegoing as my own, I have hereto affixed my signature
